Mets notes: Noah Syndergaard on disabled list

Top pitching prospect Noah Syndergaard has been placed on the disabled list with a mild strain of the flexor-pronator, which is a muscle in the elbow. He will be examined by team doctors in New York for precautionary reasons, according to a news release.

General manager Sandy Alderson said he believes the muscle flared up after Syndergaard’s last start for Class AAA Las Vegas on May 21.

"At this point we don’t have a high level of concern," Alderson said. "Any time the forearm is involved, we like to have it looked at."

Syndergaard is the top prospect in the organization and was expected to be called up around midseason. Although the strain is mild, there’s always concern whenever a pitcher deals with arm or elbow issues. There have been instances when pitchers who have undergone Tommy John surgery have dealt with this strain before the operation.

Syndergaard is 5-2 with a 4.02 ERA in 10 starts.

"We’re very concerned about it," manager Terry Collins said. "I know a lot of guys who go to the doctor and it’s nothing, but I know some who go to the doctor and it’s an issue. Any time you go in there and the word elbow shows up, especially when you throw as hard as he does, it’s a concern."

Young Jr. on DL

Outfielder Eric Young Jr. was placed on the disabled list with a right hamstring injury, and minor league outfielder Matt den Dekker was promoted.

Gee update

Starter Dillon Gee (lat), who was scheduled to throw off a mound Sunday but did not, will be reexamined and then likely head to Florida to continue his rehab, Collins said. Gee was eligible to return from the disabled list Monday.

"He’s not feeling as good as we had hoped right now," Collins said. "We’re going to take our time and let the process work.

D’Arnaud update

Catcher Travis d’Arnaud (concussion) went 0-for-4 in his second rehab game with Class AA Binghamton. He served as the designated hitter.
